With the parts in the position shown in Fig. 1, in order to remove theplug from the valve body it is only necessary to impart a slightdownward movement to the handle U, at the same time drawing the lockingplate laterally, after which the plug can be removed from the valvebody. The construction affords an extremely simple arrangement which canbe manufactured at a reasonablecost and can be readily operated. Theparts are so arranged that they can be quickly separated for purposes ofcleaning, and the structure is entirely practical for use with liquidfoods such as milk,

from the standpoint of sanitary requirements.

I claim as my invention:

1. The combination with a valve body, of a rotary plug having a reducedlower end, a removable locking member slotted to engage said reduced endof the plug and adapted to be positioned against, the valve body, saidlocking member being recessed on its upper surface to engage the valvebody, a shoulder at the end of the reduced portion of the plug, afollower arranged on the plug above said shoulder and having an inwardlydirected flange at its top, and a Copies of this patent may be obtainedfor spring positioned between said shoulder on the plug and the flangeon the follower.

2. The combination with a valve body, of a rotaryplug, a locking memberslotted to engage the plug, said locking member being disposed betweenthe valve body and the lower end of the plug and provided with a handleor projection whereby it can be positioned or removed, a followerarranged on the plug and engaging said looking member, and a springcooperating with the follower.
